Energy Isolation (Lock Out Tag Out)

Energy sources in the workplace need to be controlled and often isolated to safely access machinery or any mechanised system. Incidents occur when there’s a lack of isolation systems and a lack of knowledge about hazards associated with plant and equipment.

Energy sources in the workplace need to be controlled and often isolated to safely access machinery or any mechanised system. Incidents occur when there’s a lack of isolation systems and a lack of employee knowledge of the hazards associated with plant and equipment.

Overview

Energy Isolation (Lock Out Tag Out) course overview

A system being shut down does not mean it is safe. When isolation procedures are rushed because a task will “only take five minutes,” or assumptions replace proper verification of a zero-energy state, workers can be exposed to uncontrolled hazardous energy, with potentially devastating consequences. This Energy Isolation (Lock Out Tag Out) course builds the knowledge and skills required to safely isolate energy sources and work on plant and equipment.
 
We don’t treat isolation as an administrative process or something to rush through under pressure. Instead, our industry-experienced trainers guide learners through the practical requirements of identifying hazardous energy, applying isolation procedures, and verifying a zero-energy state. Participants develop an understanding of different energy sources, isolation equipment, lockout and tagging requirements, and the safe process for isolation and reinstatement.
 
IMPAC’s focus is on building practical capability so workers can safely carry out isolation procedures and protect themselves from hazardous energy. Participants step back into the workplace equipped to apply isolation processes with confidence, verify that systems are safe, and ensure work is carried out safely.

Curriculum

What you'll cover

This course is designed for:
  • Workers carrying out operational or maintenance duties on plant, machinery, or equipment.
  • Team leaders and supervisors responsible for ensuring safe energy isolation and reinstatement procedures are followed.
  • People responsible for isolating hazardous energy before servicing, repair, cleaning, or inspection work.
  • Workplaces wanting stronger and more consistent lockout/tagout practices as part of day-to-day risk control.

Our approach

+IMPAC's Energy Isolation (Lock Out Tag Out) training approach

This Energy Isolation training is built around the points where isolation work can break down in real workplaces: assumptions about shutdowns, incomplete isolation, weak handovers, and restarting plant before the job is properly cleared. Learners work through practical scenarios and activities that help them identify hazardous energy sources, understand isolation responsibilities, apply lockout and tagout steps, and verify a zero-energy state before work begins.

The session stays focused on what people need to do on the job. Rather than relying on theory alone, facilitators connect the training to plant access, maintenance activity, and safe reinstatement so learners can see how energy isolation decisions affect the wider job. The emphasis stays on applying isolation procedures consistently, communicating clearly during handovers, and confirming equipment is safe before work starts or plant is returned to service.
